METHOD AND ARRANGEMENT FOR MAKING NAKED FLOORING.

Application filed September 16, 1924, Serial No. 737,965, and in Sweden September 29, 1923.

The present invention relates to a method of constructing flooring consisting of iron joists with a filling of bricks between them. The method consists in the outer walls first being erected to that height at which the flooring joists are to be placed, and the bricks afterwards being laid in rows upon a suitable, removable support, the iron joists then being inserted into purposely made recesses in the bricks and simultaneously laid in their definite places in the walls, a binding liquid then being poured in the space between the bricks and iron joists and between the bricks in each mutual row, the erection of the walls then being continued so that the iron joists will be locked fast in the same, until the wall reaches the height where the next flooring is to be put in, and so on. Hitherto when laying such flooring all the iron joists were first put in their places and then the bricks laid between them in some manner or other. The insertion of the joists according to this invention can take place in any suitable manner whatsoever, for example in a transverse or longitudinal direction, provided only the bricks are properly retained between them. For laying the bricks in rows, removable supports or beams may be used.

The accompanying drawing illustrates roughly an example of the manner in which the present method is carried into effect.

Fig. 1 shows a transverse section through a portion of flooring constructed according to the invention. Fig. 2 shows how iron joists of different heights may be used in one and the same flooring. Fig. 3 shows a brick provided with a detail according to the in vention. Fig. 4 is a view on a reduced scale illustrating the manner in which the ends of the bricks are temporarily supported, portions of the walls being shown in section.

Referring to the drawings, a row of bricks 1 is laid along the iron joist 2, the ends of the bricks being formed to correspond approximately with the contour of the joist so that a portion of each brick extends between the flanges of the joist while another portion of the brick embraces one of said flanges, the bricks being supported at one end by a temporary support 9, as shown in Fig. 4, in

which figure the joist 2 is shown with its ends resting on top of the side walls 10. After the first row of bricks has thus been laid, a second joist 3 is inserted in a transverse direction in its proper place and the temporary support removed for supporting the next row of bricks, and so on. Before the iron joists are fixed in their places the wall has thus only been [erected to that height where they are being fixed.v Then a binding liquid is poured into the channels formed by the grooves 4 (Fig. 3), and also into channels formed by grooves (not shown) 1n tl1e contiguous transverse surfaces of the bricks and in the space 5 between the bricks and the iron joists. When the bricks are provided with the grooves 6 shown in Fig. 3, the penetration of the binding liquid intothe space 7 below the flange of the iron joist is facilitated. In Fig. 1 are shown the nailing strips 8. For the lower iron joist 2 in Fig. 2 a higher nailing strip is used and for the higher iron joist 2 a lower one. By pouring in the binding liquid in the aforesaid manner the bricks are securely bound together not only between themselves but also to the iron joists, so that the entire flooring forms a single cohesive unit.

The lower surface of the flooring forms, without any further treatment except a slight smoothing at the joints, a ceiling surface ready for whitewashing or painting. The space or interstice below the joists can naturally be retained unfilled in order to further increase the sound insulation. It is evident that the flooring can be made throughout its entire height of the bricks and filling material as above described, or formed of concrete above the height of the joists and thus form a first class concrete flooring of a single piece.

vWhat I claim is A method of constructing flooring of iron joists with a filling of bricks between them, which consists in first erecting the walls only to the height at which the flooring is to be placed and thereafter alternately laying a row of bricks upon a suitable removable support and placing a joist in contiguous relation to said row of bricks and simultaneously laying said joist in its definite places on the walls, said rows of bricks having recesses approximately corresponding in shape to the contiguous sides of the oists, pouring it binding liquid into the space between the bricks and the iron joists and between the bricks in contiguous rows, and continuing the erection of the Walls to the height Where the next flooring is to be constructed thereby to secure the iron joists therein. 10

In testimony whereof I have signed my name to this specification.
